 #
 # === Parameters
 #
+# [*certificates_specs*]
+#   (Optional) The specifications to give to certmonger for the certificate(s)
+#   it will create.
+#   Example with hiera:
+#     apache_certificates_specs:
+#       httpd-internal_api:
+#         hostname: <overcloud controller fqdn>
+#         service_certificate: <service certificate path>
+#         service_key: <service key path>
+#         principal: "haproxy/<overcloud controller fqdn>"
+#   Defaults to hiera('apache_certificate_specs', {}).
+#
+# [*enable_internal_tls*]
+#   (Optional) Whether TLS in the internal network is enabled or not.
+#   Defaults to hiera('enable_internal_tls', false)
+#
+# [*generate_service_certificates*]
+#   (Optional) Whether or not certmonger will generate certificates for
+#   HAProxy. This could be as many as specified by the $certificates_specs
+#   variable.
+#   Note that this doesn't configure the certificates in haproxy, it merely
+#   creates the certificates.
+#   Defaults to hiera('generate_service_certificate', false).

+#   (Optional) The network name where the heat API endpoint is listening on.
+#   This is set by t-h-t.

+#
 # [*step*]
 #   (Optional) The current step in deployment. See tripleo-heat-templates
 #   for more details.
